NOZZLE.

' Application filed April 13, 1916. Serial No. 90,892.

a To all whom it may concern:

Be it known that I, CHARLES H. STEPHAN, 'a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Nozzles, of which the following is a specification, reference being had therein to'the accompanying drawing. This inventionrelates to nozzles. The object of the invention is to provide a nozzle with the parts thereof so arranged and organized that thestream will be directed therefrom flared and spreading, producing bodiment of my invention; Fig. 2 is a vertical section through the same; Figs. 3 and 4 are plan views, partly'in section, of modified forms of nozzle; and Fig. 5 is a sectional view showing a device for adjusting the size of the orifice of the nozzle.

In the embodiment of the invention shown in Figs. 1 and 2 I have provided the usual attaching member 1 with an adjustable coupling 2 mounted at one end thereon. The opposite end of the member 1 is provided with a shell comprising a conical nozzle portion 3 which converges to a reduced orifice'r and is here provided with a flared portion or extension 5. The flared extension, as will be seen by considering Fig. 1, diverges considerably in plan and converges in section as shown in Fig. 2. As there shown the depth is very much restricted compared with the depth of the portion 3. The flared portion 5 is provided with a narrow orifice 6 extending from end to end thereof trans versely, as shown in Fig. 1. Surrounding the 'portions 3 and 5 is a second shell or member 7 which incloses, but is separated described serves to cause the stream to spread out and flare and to be ejected The portion of the member 7 ing feature of the member 3 and the restricted opening 4 the fluid ismore or less crowded in passing through the same and the pressure, as the fluid flows through the same into the flared portion 5, causes the fluid to spread and accommodate itself to the flare of the portion 5. The depth of the stream will also be lessened proportionately. It will then be apparent that the stream will issue from the orifice 6, greatly spread out and attenuated. The thin flared member 7 will also tend to accentuate the attenuation and the flaring form of the stream. The lower side of the member 7 is extended beyond the orifice 9, as shown at 10, and the upper surface of the member 7 is provided with a transversely extending rib 11 adjacent the orifice 9, to prevent the pressure of the fluid going through the orifice from causing the upper side of the member7 to bulge and vary the size of the orifice. In a like manner the lower side adjacent the orifice is also provided with a combined reinforcing strip and rest 12. Immediately infront of the orifice 9 and located upon the projecting portion 10 of the lower side of the shell is a spray-forming abutment or deflector 13. This abut-.

ment, in the present instance, is formed from tached at 15 to the outer end of the flared portion 5 of the inner shell. The form shown in Fig. 1 is more durableand stronger, protects entirely the inner portions 3 and 5 and presents a neater appearance. The form shown in Fig. 3, however, when in operation produces the same results as the form shown in Figs. 1 and 2. But in the form shown in Fig. 3 the cost of material is less and the device ischeaper. IVith the exception that the shell 7 is attached to the flared portion 5 instead of to the memher 1, as shown in Fig. 1, the structure is otherwise the same as in the form first described.

In some cases it is desirable to omit the inner shell entirely and in Fig. 4 T have 1 Letters, Patent, is

shown such a construction. The shell 16 shown in Fig. 4 is attached to the coupling member 1 in a manner similar to that shown inFig. 1. 'The structure of the shell is identical with the structure of the outer shell 7 shown in Figs. 1 and 2, the inner portions 3 and 5 being omitted however.

In Fig. 5 I have shown a novel means for U-shaped support 17 which extends from end to end and parallel with the orifice 18. The .U-shaped member is provided with a screw-threaded opening 19 in which is located a knurled adjusting screw 21 having its end in engagement with the top of the shell. It will be seen that by adjusting this screw the uppersurface of the shell will be more or less bent, thus restricting the size of the orifice. It is desirable when this form is. used to omit the reinforcing rib 11 shown in Fig. 2.- 7

While I have shown and described one embodiment of my invention and a modification thereof it will be understood that this has been chosen for the purposes of illustration only, and that I do not desire to be limited to the details of construction shown --'and described, for obvious modifications will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new'and desire to secure by 1. In a nozzle, aninner shell having an orifice, a surrounding shell having sides flaring from a point to the rear of said orifice and projecting in'front thereof, said sides converging toward each other in front of said orifice, forming an elongated orifice in front of said first-mentioned orifice and a deflector extending from end to end of said last mentioned orifice and in front of the same. g

2. In a nozzle, a flared shell having a nar row elongated orifice and means for further spreading out and attenuating the stream from said orifice comprising a surrounding shell having ared sides adjacent the first-mentioned shell. and converging forwardly and forming a narrow elongated orifice, the arrangement of the shells relatively to each other and their respective sizes serving to so attenuate and spread 'outthe stream. I

3. In a nozzle, a flared shell having a narrow elongated orifice and means for fur-' ther attenuating and spreading out the stream from sald orifice comprising a surrounding shellhaving flared sides pro ecting beyond saidorifice converging for-f wardly and likewise provided with a narrow elongated orifice, said shells being so arranged relatively to each other and of such comparative sizes that the last-mentioned orifice is adapted to receive the stream from said first-mentioned orifice only.

41. In a nozzle, an inner shell having a narrow elongated orifice and means for spreading out and attenuating the stream issuing from said orifice comprising a surrounding shell having flaring sides projecting in front thereof and converging forwardly toward each other forming an elongated orifice in front of the first-mentioned orifice, the arrangement of the shells relatively to each other and the respective sizes serving to so attenuate and spread out the stream.
